I whish to install IPSEC vpn client. During installation I bump into following error message :

"Files Needed: The file 'dneinobj.dll' on Deterministic Network Enhancer Disk is needed.

  Type the path where the file is located, and then click OK"

I have been calling the vendor of the computer, to have them sending mee the file "dneinobj.dll". They claim that this is suppose to

follow the download of the Cisco VPN client that I'm trying to install. I find that strange since I have no problems on other computers installing this client.   

I have tried to google on the internet, but have had no luck finding a problem similar to mine.

Not sure if this is the right place to ask this kind of question, but I hope somone have a solution to sugest.

It seems to mee that I just need to find a copy of the file "dneinobj.dll", or is this a symptom of another problem.

The computer I try installing the client is for Dell Optiplex FX160 - it is a thin-client.
